Download and Install AOSP Android 10 Q for Samsung Galaxy J7

This guide covers installing an AOSP-based Android 10 custom ROM (crDroid) on the Samsung Galaxy J7 2015 (SM-J700F, codename j7elte). Android 10 was Google’s tenth major release and the first to drop the dessert naming. Since Samsung never shipped Android 10 to the J7, a community ROM is the way to run it.

Samsung Galaxy J7 overview

The Galaxy J7 (2015) has a 5.5-inch HD Super AMOLED display, an octa-core Exynos 7580, 1.5GB of RAM, and a 3,000mAh battery. It shipped on Android 5.1 Lollipop and ended on Android 6.0.1 Marshmallow officially.

6. Reboot into the new system. The first boot takes a few minutes.

FAQ

Did the Galaxy J7 get Android 10 officially?

No. Samsung ended updates at Android 6.0.1 Marshmallow, so Android 10 is only available through community ROMs like crDroid.

Do I need to flash GApps separately?

Yes. Most AOSP ROMs ship without Google apps, so flash a matching Android 10 GApps package during installation if you want the Play Store.

Is this ROM stable for daily use?

As a community build it can have bugs. Check the XDA thread for the current status before relying on it as a daily driver.
